Abstract
Results are presented from the optimal operation of a fully automated robotic liquid handling
station where parallel experiments are performed for calibrating a kinetic fermentation model.
To increase the robustness against uncertainties and/or wrong assumptions about the parameter
values, an iterative calibration and experiment design approach is adopted. Its implementation
yields a stepwise reduction of parameter uncertainties together with an adaptive redesign
of reactor feeding strategies whenever new measurement information is available. The case
study considers the adaptive optimal design of 4 parallel fed-batch strategies implemented
in 8 mini-bioreactors. Details are given on the size and complexity of the problem and the
challenges related to calibration of over-parameterized models and scarce and non-informative
measurement data. It is shown how methods for parameter identifiability analysis and numerical
regularization can be used for monitoring the progress of the experimental campaigns in terms of
